HAZARDS AFFECTING LAND

SURF

Large swells produced by Ana are expected to build over the eastern end of the main Hawaiian island chain through Friday morning. These large swells will continue to spread up the island chain through the weekend. Surf produced by these swells could potentially be damaging along exposed south and southeast shorelines beginning late Friday and Saturday, and persisting through the weekend in some areas.

RAINFALL

Heavy rainfall associated with Ana may reach the Big Island of Hawaii Friday afternoon, with total rain accumulations between 6 and 12 inches expected. Heavy rain could potentially affect the other islands Saturday and Sunday. This rainfall could cause life-threatening flash floods and mud slides.
